MPU-9250 Equivalent & Substitute Parts

Part Overview

The MPU-9250 is a 9-axis inertial measurement unit (IMU) integrating a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer in a single 24-pin QFN package. It provides motion sensing data via I2C and SPI interfaces and operates across the industrial temperature range of -40°C to 85°C.

The MPU-9250 is classified as obsolete. Finding equivalent substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity where new production is unavailable.

Substitute Part Grouping Explanation

Substitute parts for the MPU-9250 must satisfy the following criteria to ensure functional and mechanical compatibility:

• Sensor Configuration: Must integrate accelerometer, gyroscope, and magnetometer in a single package (9-axis capability)
• Communication Protocols: Must support both I2C and SPI output interfaces
• Operating Temperature: Must cover the full -40°C to 85°C range
• Package Specification: Must use 24-pin QFN (3x3 mm) with exposed pad configuration for direct PCB footprint compatibility
• Mounting Technology: Must be surface mount compatible

The ICM-20948 meets all substitution criteria and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The ICM-20948 is the direct substitute for the MPU-9250 based on the following factors:

• Functional Equivalence: Both devices provide identical 9-axis motion sensing with I2C and SPI interfaces across the same operating temperature range
• Mechanical Compatibility: Identical 24-QFN (3x3) package footprint enables direct PCB replacement without layout modifications
• Product Status: The ICM-20948 is in active production with current manufacturing support, ensuring long-term availability and supply chain stability
• Regulatory Compliance: The ICM-20948 carries ROHS3 and REACH certifications, meeting modern environmental and regulatory standards
• Improved Reliability: The ICM-20948 features MSL 1 moisture sensitivity compared to MSL 3, providing enhanced reliability in humid storage and operational environments

Frequently Asked Questions (FAQ)

Q: Can the ICM-20948 replace the MPU-9250 in existing designs without PCB modifications?

A: Yes. Both devices use the 24-QFN (3x3) package with identical pinout and footprint. Direct component substitution on the PCB is possible without layout changes.

Q: Are the I2C and SPI communication protocols identical between MPU-9250 and ICM-20948?

A: Both devices support I2C and SPI output interfaces. Register-level compatibility should be verified during firmware integration, as protocol implementation details may differ between generations.

Q: What is the difference in moisture sensitivity between these parts?

A: The MPU-9250 has MSL 3 (168-hour moisture sensitivity), while the ICM-20948 has MSL 1 (unlimited moisture sensitivity). MSL 1 indicates superior moisture tolerance and lower risk of moisture-induced failures during storage and assembly.

Q: Is the ICM-20948 suitable for industrial temperature applications?

A: Yes. The ICM-20948 operates across -40°C to 85°C, matching the MPU-9250 operating range and supporting industrial and extended commercial temperature requirements.

Q: What regulatory certifications does the ICM-20948 carry?

A: The ICM-20948 is ROHS3 compliant and REACH unaffected, meeting current environmental and chemical safety regulations for electronic components.
